Webber Angle Gage Blocks permit fast, simple and accurate measurements of any angle. They are far superior to sine bar measuring methods that involve trigonometric formulae and complex stacks of gage blocks.
Webber Angle Gage Blocks come in three accuracy grades: croblox® Reference Angle Blocks (R grade) with a 1 second accuracy, steel Calibration Grade Angle Blocks (C grade) with a 2 second accuracy, and steel Working Grade Angle Blocks (W grade) with a 5 second accuracy. Each grade can be purchased individually, or in sets that will measure in steps of 1 second, 1 minute or 1 degree to suit any need.
croblox® Reference Angle Blocks with a 1 second accuracy are designed for optical use or as reference standards for autocollimators, spectrometers, or other types of optical instruments. These Angle Blocks are unsurpassed for use in aerospace, optical and precision instrument fields.
Steel Calibration Angle Blocks with a 2 second accuracy possess the same high quality as the Reference Grade Angle Blocks but are manufactured from hardened tool steel for better economy.
Working Angle Blocks with a 5 second accuracy are designed for the shop or tool room. Their longer gaging surfaces are made for use with an indicator. Additonally, these blocks reduce set-up time and minimize error in grinding both simple and compound angles.
Whether aligning a complex optical system, or inspecting a simple angle, Starrett's Webber Gage Division has the Angle Block solution to fit your requirements and your budget!
